Hi All,

Reading my Renewable Energy World mag I found this interesting article on swept back semi flexible WG blades though in huge sizes applies somwhat to ours and talks about how mine works though I did mine 30 yrs ago, well before they 'discovered' the same features . Note how they mention it increases low wind performance, widens preformance range and decreases high wind stresses, weight just as I've been saying here.
